As c early-shown in Figure 3, the 'arm 18 struction it will be -apparent that the arm '10 is free to yswingend in doingso. will swing the arm 18 in the slot 20.

From the foregoing descriv tion of the various parts of the device, t e operation thereof. may 'be readily understood, If it isdesired to use the instrument as an ordinary phonoaph, the desired record mayv be obtained omthe record com artment 5 andbe placed on the turntab e9. The machine may now be operated in the ordinary manner, the sound waves, passing through the arm 10 and the horn 11.

When it is desired to listen inwithV Athe radiophone, the knobs on the receivingj set 15 may be turned soas to obtain the uired wave length. The loud speaker 1v it the arms 18 andl() and out through .the horn 11,` where they can be readilyheard by all in the room.

In Fig. 4, I have shown a lmodified form ofthe device. This form ofthe device is identical with the form heretofore ldescribed except that the tone arm 18 which communicates with the loud speaker 17 isconnected directly to the horn 11 instead of to the tone arm 10.. In this instance the 'de-V vice resembles -the ordinary' Aphonograph when received from above the artition 19. It will also be apparent thatin this form of the device, the arm 18 doesnotswing when the arm 10 is swung. Asheretofore stated, with this instrument are connected to the same horn. The two devices may be oper-ated in unison or separately. The device is eicient for. the purprojects throughv an arcuate.
